Beyond unacceptable... I purchased three of their small (.03g) vape pen cartridges during a sale, I have been using a different dispensary for the last year and a half without incident but 50% seemed too good to pass up. By the time I had gone through 1 and a half of them my lungs had become so inflamed and tight that I felt like I couldn't breathe. 24 hours after stopping the use of their product, I walked up 2 flights of stairs and felt like I was almost suffocating, developed a headache and stayed that way until I went to sleep. When I woke the next day, I sent Curaleaf an email explaining everything I just told you as well as the fact that third cartridge seemed to have leaked all over the inside of the packaging but I wasn't concerned about that at this point. Their response to one of thier customers telling them that their product caused serious lung damage?, "thanks for letting us know. Please send us pictures of the product stickers and receipt.". I sent the requested pictures and have heard NOTHING ELSE from them. I ended up having to go to the hospital where the physicians their felt it was serious enough to give me a triple dose of albuterol, 3 ccs IV steroids and a take home prescription for steroids and an asthma inhaler because, due to the damage and irritation in my lungs, my O2 was steady 89-91 when it should never be below 92. That is precisely how much Curaleaf cares about their customers. There are too many other choices.
